1. Scope 1.1
This Standard provides requirements for rigid polyvinyl chloride (PVC)
injection-moulded fittings intended for use in pressure applications such as
water mains, water service piping, process piping, and fire lines. Fittings
covered by this Standard are suitable for use with PVC pipes having outside
diameter (OD) dimensions of cast iron pipe. Only one pressure rating, 1620 kPa
(Class 150), is included that is suitable for use with compatible OD PVC pipes
having a dimension ratio (DR) of 18 or more. The fittings have gasketed
joints.
Note: If PVC fittings are to be used in other than water applications, the
manufacturer should be consulted. 1.2
This Standard includes requirements for materials, quality of work, dimensions,
marking, long-term performance under sustained hydrostatic pressure, and
injection-moulding quality. 1.3
The values given in SI (metric) units are the standard. The values in
parentheses are for information only.
